Rurubu Taipei 25 and CREA May 2020, a set of two books. The guidebooks offer a different perspective and were helpful. I've uploaded the table of contents, so please take a look. There are no markings. I only flipped through Rurubu at home, and it's in good condition. I haven't taken it out of the house. CREA has a slightly bent corner. Please purchase if you understand.
